jimthompson5910 (jim_thompson5910):

(f + g)(x) means f(x) + g(x)

jimthompson5910 (jim_thompson5910):

so you simply add the two functions and simplify if possible

OpenStudy (anonymous):

so it would be sqrt of 12x?

jimthompson5910 (jim_thompson5910):

can you draw out the functions?

OpenStudy (anonymous):

the x's come out as one so it would be x sqrt of 12

OpenStudy (anonymous):

yes one second

jimthompson5910 (jim_thompson5910):

wait, 6+9 or 6x+9 ?

OpenStudy (anonymous):

6x+9 im sorry

jimthompson5910 (jim_thompson5910):

so you just add them and you cannot combine like terms (because there are none)
